SysEx is a free MIDI librarian program for the Macintosh. SysEx can transmit and receive system exclusive (sysex) messages via MIDI and can save and load these messages to and from disk.
SysEx now features user-configurable settings to specify a pause between system exclusive messages when transmitting and to specify the receive buffer size, which can now be as large as 1024 KB (1 MB) and as small as 64 KB.
The highlight of this release is that a long-standing problem with receiving into SysEx using Midiman (M-Audio) MIDISPORT USB interfaces now appears to be resolved. The issue may have affected other interfaces (such as the Steinberg USB2MIDI) as well. The manual has also been expanded to add additional troubleshooting information
